AccuSharp Deluxe Tri-Stone Knife & Tool Sharpening System Kit, Slip Resistant, Mountable Rubber-Grip Base, Quickly Sharpens, Restores, Repairs & Hones All Types of Blades & Knives, Black

I didn't buy this on Amazon--I didn't even know these existed. Rather, I stumbled upon it at a local ranch supply after throwing away all my totally useless knife sharpeners and looking for a simple stone. I found it here on Amazon when I recommended it to a friend and wanted to see if I could find a source for him (he doesn't live in my town). I see other reviewers have downrated this unit for grit size—I know nothing about that. And I agree with one review that said that it leaves dust after sharpening: it does. Nevertheless, it WORKS, and well! My old knife sharpeners were all garbage. I purchased a top-quality chef's knife a few years back—first quality knife I've ever owned—and when the edge dulled, none of my knife sharpeners could give me back that edge. This unit did! We're talking shaving-sharp. If there's such a thing as "sharpness rays", this will create them. Okay, maybe the other reviews have a point and there are better sharpening stones. But from now on, when and if this one wears out, I'll replace it with a STONE again: never, ever will I buy a "knife sharpener" again. I've had three, including a "professional" electric one and all went in the garbage. Heck, people used to sharpen swords and knives with rocks: that should tell us SOMEthing.

Happy with the quality and price

Boxes on the last few orders have been open and torn and some items were broken

Like sharpening with chalk so much stone removed with each stroke. Found large granules in the stone.

These are poor quality and the "fine" stone isn't very fine. It's basically a red brick that wears quickly.
